LIVECHART2 as ADDIN in SOLIDWORKS

[SmallFred]

I develop an addin in SOLIDWORKS (CAD software) and I want to use LIVECHART2.

I try it in a standard WPF application (.NET Framework 4.8) and it works well. But if I integrate the exactly the same example (Radar CHART example) inside my ADDIN in solidworks, no crash but impossible to display it. Nothing happen

Thanks for your help

I found the problem. Some dll were missing. But it very strange why no message error is displayed
